Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic metal welding, in particular to an ultrasonic metal welding machine frame. Background Art

[0002] Ultrasonic welding uses ultrasonic waves to vibrate away oxides on the metal surface, and utilizes the protruding surface of the weld to continuously weld, thereby increasing the contact area of ​​the weld and forming weld points by increasing the temperature of the weld area.

[0003] However, the existing welding machine cannot be adjusted in height, resulting in the welding machine being unable to weld workpieces of different sizes, thereby affecting efficiency.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN219004915U discloses a metal ultrasonic welding machine frame. The distance between the ultrasonic welding machine and the base can be adjusted through a lifting assembly, which facilitates welding of workpieces of different sizes and improves the use effect of the equipment. The output port, input port, output pipe and input pipe can allow the water in the water tank to circulate in the cooling pipe, take away the heat in the base, help the base to cool down quickly, and prevent the base from heating up after long-term operation, affecting the service life of the equipment and the welding effect of the workpiece.

[0005] The above-mentioned device uses a lifting assembly to adjust the height of the welding machine during use, thereby facilitating the processing of workpieces of different sizes. However, in the existing technology, due to the limitation of the horn length of the conventional horn welding head, the welding surface of the welding head is worn. After the surface is reduced and ground, the horn length of the welding head will be further reduced, making the welding head unusable. Utility Model Content

[0006] The purpose of the utility model is to provide an ultrasonic metal welding frame to solve the problem in the above background technology that the welding head of the horn welding head is easily damaged due to welding wear.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an ultrasonic metal welding frame, comprising an ultrasonic triple drive cylinder and a housing, and further comprising:

[0008] A pneumatic rod is movably mounted on the inner side of the ultrasonic triple drive cylinder, a clamping block 1 is fixedly mounted on the bottom surface of the pneumatic rod, a protective shell is movably mounted on the inner side of the clamping block 1, and a welding mechanism is provided between the pneumatic rod and the protective shell;

[0009] A fixing seat is fixedly installed on the outer surface of the shell, a second clamping block is movably installed on the outer surface of the protective shell, and a clamping mechanism is provided between the fixing seat and the second clamping block.

[0010] Furthermore, a washer is fixedly mounted on the outer surface of the pneumatic rod, and a limit nut is fixedly mounted on the outer surface of the pneumatic rod, and the pneumatic rod and the washer form an integrated structure.

[0011] Furthermore, a transducer is fixedly mounted on the inner side of the housing, an array receiver is fixedly mounted on the outer surface of the transducer, and a vibrator is fixedly mounted on the inner side of the transducer.

[0012] Furthermore, a horn assembly is fixedly mounted on the outer surface of the vibrator, a fixing sleeve is fixedly mounted on the outer surface of the horn assembly, and a connecting rod is fixedly mounted on the outer surface of the horn assembly.

[0013] Furthermore, a positioning plate is fixedly mounted on the outer surface of the connecting rod, the welding mechanism includes a positioning plate, and a horn welding head is movably mounted on the inner side of the positioning plate, and the connecting rod and the positioning plate form an integrated structure.

[0014] Furthermore, a screw is threadedly installed on the inner side surface of the clamping block 2, a fixed block is fixedly installed on the top of the clamping block 2, and the clamping block 1 is movably installed on the outer surface of the fixed block, and the fixed block and the clamping block 1 form a snap-fit ​​structure.

[0015] Furthermore, a clamping block 1 is threadedly installed on the outer surface of the screw, a locking block is fixedly installed on the bottom surface of the clamping block 1, the clamping mechanism includes a locking block, and a clamping block 2 is movably installed on the outer surface of the locking block, and a clamping structure is formed between the clamping block 1 and the clamping block 2.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The ultrasonic metal welding frame has the following specific contents:

[0018] 1. When clamping block 1 and clamping block 2 clamp the welding mechanism, by starting the ultrasonic triple drive cylinder, the ultrasonic triple drive cylinder drives the pneumatic rod to move up and down, and the pneumatic rod drives clamping block 1 to move up and down, thereby facilitating the adjustment of the height of the welding mechanism and facilitating the processing of workpieces of different sizes;

[0019] Furthermore, the transducer is started to drive the array receiver to work, the array receiver drives the vibrator to work, the vibrator drives the amplitude transformer assembly to work, the amplitude transformer assembly drives the connecting rod to work, and the connecting rod drives the horn welding head to work, thereby performing stable welding on the workpiece. Moreover, by designing a raised boss on the right root of the horn, not only can the horn length of the welding head be lengthened, but also the vibration uniformity of the welding surface of the welding head is improved, thereby ensuring the quality of the welding joint of the welding workpiece.

[0020] 2. Manually clamp the clamping block 1 and the clamping block 2, and embed the fixing block and the clamping block in the clamping block 1 and the clamping block 2 respectively. Manually fix the screws in the clamping block 1 and the clamping block 2 to increase the overall stability and prevent them from falling off during processing.

[0021] Furthermore, the positioning plate is fixed by a connecting rod, and the positioning plate fixes the horn welding head. By increasing the length of the horn welding head, the welding head can be ground down after the welding surface is worn, which not only improves the service life of the welding head, but also reduces the cost of welding.
